"Echo" is the third and final single from Trapt's eponymous debut album.

In Greek mythology, Echo (; , Ēkhō, " echo", from ἦχος (ēchos), "sound") was an Oread who resided on Mount Cithaeron. Zeus loved consorting with beautiful nymphs and often visited them on Earth. Eventually, Zeus's wife, Hera, became suspicious, and came from Mt. Olympus in an attempt to catch Zeus with the nymphs. Echo, by trying to protect Zeus, endured Hera's wrath, and Hera made her only able to speak the last few words spoken to her. So when Echo met Narcissus and fell in love with him, she was unable to tell him how she felt and was forced to watch him as he fell in love with himself.

The Exoplanet Characterisation Observatory (EChO) was a proposed space telescope as part of the Cosmic Vision roadmap of the European Space Agency, and competed with four other missions for the M3 slot in the programme. On February 19, 2014, the PLATO mission was selected in place of the other candidates in the programme, including EChO.

EChO would be the first dedicated mission to investigate exoplanetary atmospheres, addressing the suitability of those planets for life and placing the Solar System in context. EChO is intended to provide high resolution, multi-wavelength spectroscopic observations. It would measure the atmospheric composition, temperature and albedo of a representative sample of known exoplanets, constrain models of their internal structure and improve our understanding of how planets form and evolve. It will orbit around the L2 Lagrange point, 1.5 million km from Earth in the anti-sunward direction.

Echo is the tenth studio album by Tom Petty and the Heartbreakers. First released in April 1999, the album reached number 10 on the Billboard 200 aided by the singles "Free Girl Now", "Swingin'" and "Room at the Top", which hit numbers 5, 17 and 19 respectively on Billboards Mainstream Rock Tracks in 1999. The album was the band's last collaboration with producer Rick Rubin, and was also the last to feature contributions from longtime bassist/vocalist Howie Epstein, who died of a heroin overdose in 2003. Echo was certified Gold (500,000 copies sold) by the RIAA in July 1999, only three months after it was released. Echo is the only Heartbreakers' album to contain a lead vocal from another member of the band: Mike Campbell on "I Don't Wanna Fight". An outtake entitled "Sweet William" appeared as the B-side (or second song) on the "Room at the Top" CD single.

Only certain songs were played on the band's tour that year. The record was largely written during a period when Petty was going through a painful divorce (influencing the lyrics of songs such as "Lonesome Sundown" and the title track), and Petty has cited that as the reason for his preference not to play any songs from the album in concert. However, "Room at the Top", "Free Girl Now" and "I Don't Wanna Fight" all appear in the concert film High Grass Dogs: Live at the Fillmore and a version of "Billy the Kid" appears on The Live Anthology.

In computing, echo is a command in DOS, OS/2, Microsoft Windows, Singularity, Unix and Unix-like operating systems that outputs the strings it is being passed as arguments. It is a command typically used in shell scripts and batch files to output status text to the screen or a file.

Many shells, including all Bourne-like (such as Bash or zsh,) and Csh-like shells implement echo as a builtin command.

Echo is a studio album released by jazz pianist Dave Burrell. It was recorded on August 13, 1969 and first released as an LP album by BYG Actuel. It was re-released twice, first again on LP by Get Back Records in 2001 before finding its way to compact disc in 2004 via Sunspots Records.

Burrell had been part of an all-star group led by Archie Shepp that played during the 1969 Pan-African Festival in Algiers. While there, French journalists from Paris were on hand and mentioned to Burrell the possibility recording in the city. Deciding on such a venture, Burrell remarked that he "remembered the sound of the ambulances and the police cars in Algiers and that unstable interval of an augmented fourth and thought that was the interval that I wanted to put into 'Echo'." The recording was Burrell's way of honouring the group, since all were involved in the album.

It has been said that the album as a whole "is [a] monster of an LP" and "a curiously schizophrenic set."

In computer telecommunications, echo is the display or return of sent data at or to the sending end of a transmission. Echo can be either local echo, where the sending device itself displays the sent data, or remote echo, where the receiving device returns the sent data that it receives to the sender (which is of course simply no local echo from the point of view of the sending device itself). That latter, when used as a form of error detection to determine that data received at the remote end of a communications line are the same as data sent, is also known as echoplex, echo check, or loop check. When two modems are communicating in echoplex mode, for example, the remote modem echoes whatever it receives from the local modem.
